I had these errors come up this morning, on my way to work, driving with the cruise one at 64 mph. Car still drove okay, but DSC is disabled and I couldn't re-activate it.
From what I read, there are a few different reasons for this to happen:
1. Faulty wheel speed sensor
2. Faulty steering angle sensor
3. Faulty wheel bearing
4. Faulty DSC hydro unit (fix could be as expensive as $2,400.00)
I'm glad I bought extended warranty.
